pyzipper
========

A small tool to package up a Python program and associated data files
as a single executable zip file.

All the facilities for this are already built into Python, this script
just ties it all together with a bow.

`demo1` and `demo2` are two trivial sample packages.

Tested with both Python 2 and Python 3, should work with either.

How it works
------------

This relies on two somewhat obscure Python features:

* The `zipfile.PyZipFile` class's ability to construct an executable
  ZIP file and populate it with Python modules, packages, and data;
  and
  
* Python's ability to treat a zip file as equivalent to a directory
  tree on `import`.
  
`demo1` takes advantage of a third obscure feature: the `pkgutil`
library's ability to load data files via the `import` system.
